Sonos surprise

Hey guys. I just wanted to share an experience that I had, which really surprised me. On a whim, I picked up a Sonos Connect (ZP90). I wanted to try something easier. I quickly got tired of dealing with a dedicated music server and the Apple TV and everything associated with it.

Anyway, I got the Sonos unit home, connected it to my NAD T163 Pre/Pro via glass optical and did some A/B comparisons with the Apple TV rig and they sound EXACTLY the same. At this point it was a toss up as to whether I was going to keep the Sonos or return it. I played around with it last night and most of today, all the while assuming that the DAC in the NAD would be superior to that of the DAC built into the Sonos.

Well, being bored, I decided to try out the internal DAC in the Sonos, so I grabbed an IC and went to work. What do you know? It sounded a bit better. My little 685s that I have sitting in shelves actually sounded more full.

So...I got to wondering what would happen if I just pulled the NAD all together and connected the Sonos directly to the amp (HK PA5800) and switched the output to variable so that I could use the Sonos to control the volume.

What a surprise I got. The sound stage got BIG and WIDE. I was listening to the rig for a good half an hour before I realized that my sub wasn't even working.

In any case, I just wanted to share the experience. For me, it turns out that less is more. The NAD was definitely doing a job on the signal going through it.

I've found the Sonos to be a very nice compromise. To say that it is easy to use would be an understatement. I have it reading my music off of a USB drive that I have connected to my NetGear router. I just plugged the Sonus into the router and it read everything the way it should have. When I want to add music to my library, I just use a laptop with iTunes and I have my USB drive set as my iTunes directory. I rip a CD and it goes straight to the USB drive. The Sonos re-indexes the music once a day, so I don't even have to worry about it.

I also have to say that the Sonos is a very well thought out product, especially the software. Now, listening to music is as simple as pulling out my iPhone, iPod or iPad and hitting play.

The one big drawback to the Sonos is that it is only capable of playing 16 bit 48khz files, tops. Anything more and it just won't play it at all. For me, this is fine, since I get most of my music from ripping CDs and very little of what I like is available via HD downloads, most of it being standard 16/44.

Now I'm wondering if going with an out board DAC and getting my Sonos modded might be worthwhile. I'm really liking the idea of having nothing to deal with to listen to some good sounding music. Right now, my system consists of the Sonos, an amp and a pair of speakers.

Sonos is really all they say it is. One of the few products that delivers as promised. I was an early adopter in 2005. Has gotten better and better. Not really hi fidelity for serious listening but for a whole house audio or just fun it cant be beat.

I like the Sonos stuff. It's a lot better than a lot of people here think it is.

I bought the Apple TV 1 for a few 2 reasons: I can synch my music to its hard drive, eliminating the need for my computer to be running; and cost. Sonos didn't have an iPhone remote app at the time. Once I have a home where I can have a few zones, I'll go with a Sonos.

One Sonos product that gets no respect is the amplified streamer. It can't compete with $10k amps, but that doesn't make it junk. I've heard it set up with some good speakers that are relatively easy to drive, and I've always been impressed. They shouldn't be able to do Vienna bookshelves justice, yet they sounded far better than I expected. Anything more than what they did is a waste of money in a bedroom, office, dining room, etc system IMO. I'd never replace my Bryston B60 with one, but it'll easily make a secondary system sound great. I'd love to hear it with some Focal Chorus 705Vs.

As a curiosity question or two...
Did you have the ATV 1 or 2? Did you try it's analog outs like you're doing on the Sonos? My ATV1's analog outs are sufficient for background listening, but my Rega DAC wipes the floor with it, as it should considering the price.

I have the ATV 2 and it has no analog outs. Strictly either HDMI or Toslink. I'm actually finding the Sonos to be more convenient than the ATV for adding music in my setup. With the NAS (sort of) setup, I just rip from a laptop that has the NAS as a target and it goes straight there. I have the Sonos reindex and that's it.

I gotta admit that the Sonos is turning out to be a lot of fun. Just today, I had a bunch to do around the house. I just set it to shuffle all of the songs in my library and let it go. It was really handy being able to skip songs and adjust the volume from my iPod without having to worry about line of sight or a commplicated rf setup.

I am, however, starting to notice some negatives though. When I turn it up, I am noticing an edge on the top end. I'm really hoping that the new DAC will take care of that.

On another note, I started thinking. How on earth can I use the Sonos as a Pre when my DAC gets here. I mean, how can you attenuate a digital signal without affecting the quality of the signal? I'm almost starting to think that I might have opened a can of worms with this Sonos rig. I really want to be able to continue to control the volume with the Sonos, but would also really like to retain sound quality. Oh well, I'll have to put some more thought into it. I'm still seriously considering going with a passive Pre, like the Axiom.

The reason is that one thing I noticed when I was running the NAD as a Pre, using the digital out on the Sonus, was that if I had nothing playing but turned the volume on the NAD all the way up, I got noise. Like a hiss/hum. I don't get this when I'm running the Sonus directly into the amp. All I get is dead silence.

Like I said, more thought. What I'm mostly worried about is that I read something about the method of attenuating the digital signal and over driving the DAC with too much signal and then getting signal degradation when you turn it down too far.

I really need to find a new interest/hobby. My head is starting to hurt.

This is the noise floor of the preamp. Every product has a noise floor; some are just louder than others.

Out of curiousity, did you hear this hiss/hum with no music playing at a volume position that you normal listen at? If it's not audible at the level you normally hear at and a bit higher, it's kind of nitpicking, isn't it? If it doesn't occur at any level you'd listen at, what's the difference?

Please don't take my post as derogatory. Not the intent whatsoever.

The fact that the hiss/hum was audible at all just bugs me; and no, I couldn't hear it while listening to music.

Oddly enough, I got my Emotiva XDA-1 in today. Although I don't have the proper cabling to hook everything up right yet, I did some piece meal patch work with some cables just to get it up and running.

First to address the hiss/hum, I first hooked everything up to the XDA-1 and then ran that to the NAD Pre/Pro (not using the DAC built into the NAD), no hiss/hum. Maybe it had something to do with the internal DAC on the NAD.

Anyway, I went ahead and used the NAD as the Pre/Pro with the XDA-1's volume set on 80. It was very nice with both CD's and through the Sonos. More detail, wider sound stage, the whole nine yards. I think this says a lot with regard to the quality of the internal DAC on the Sonos and that of the NAD. The XDA-1 is an improvement over both of them.

Now, where I really saw the improvement was when I pulled the NAD from the system all together and just used the XDA-1 as a Pre. Considering what I'm used to (mid-fi at best), I was stunned. I wish I had done this a long time ago.

Anyway, back to the point; the Sonos is very nice and CONVENIENT. I think I'm going to keep it, especially after the improvements that I got with the new DAC.

The NAD T163 is going up on ebay. I don't need it any more. I'm going to start experimenting with using the volume control on the Sonos with the DAC and see how that sounds.
